Find the greatest possible error for each measurement.<br> 10 1/8 oz
scoray [572]

<u>Answer:</u>

0.0005 oz

<u>Step-by-step explanation:</u>

Usually, the greatest number that is allowed for approximation, assuming that the number itself is obtained by approximation, is the greatest possible error of it.

It is normally half the place value of the last digit in a number.

Like here we have 10\frac{1}{8} oz which is equal to 10.125 oz. The last digit is 5 which is at the thousandth place (0.001) so the greatest possible error for this would be its half.

\frac{0.001}{2} = 0.0005 oz

Arrange in descending order 1/2, 3/4, 2/3​
Anastaziya [24]

Answer:

The question is asking which numbers are larger with respect to one another. An easy way to do this is to convert to decimals, or just memorize it. 1/2=0.5, 3/4=0.75, 2/3=0.666666. So descending order (largest to smallest) 3/4, 2/3, 1/2.

Someone please help me with this and explain it please.

<h3>Answer: Choice D) \sqrt{34}, 6, 2\pi, \sqrt{42}</h3>

===========================================

Explanation:

Use a calculator to find the decimal form of each of the following below (values are approximate; rounded to 2 decimal places)

  • 2pi = 6.28
  • sqrt(42) = 6.48
  • sqrt(34) = 5.83

We see that the order of the decimal values is: 5.83, 6, 6.28, 6.48

So the order of the terms, from smallest to largest, is \sqrt{34}, 6, 2\pi, \sqrt{42}

On Monday, Harold picked up four donuts and five large coffees for the office staff. He paid $ 6.33  
sveticcg [70]
The equation would be 4x+5y=6.33 and 3x+3y=4.11
so from their you would do the calculations and get 0.52 and 0.85
To make sure the caluclations aare right you just hae to put in the numbers for the x and y
4(0.52)+5(0.85)=6.33
So 1 donutis $).52
1 large coffee is $0.85
